Patent JP-H06261457-A (JP)
Title: Intersystem power interchange controller
Inventor: ONABE MINORU
IPC: H02M5/451
Filed: 1993-03-05
Abstract: PURPOSE:To make it possible to perform high speed control, interchange of effective power and compensation of reactive power by using a voltage type inverter. CONSTITUTION:A frequency control system 7A amplifies the deviation between a DC voltage setting Vsel and an output effective power P1I of voltage type inverter 1A and controls the frequency of an inverter 1A through a phase shifter 10A and a gate control circuit 11A, thereby controlling a DC voltage VDC in constant state. On the other hand, the control system 7B amplifies the deviation between an effective power set value Pset to be interchanged and power P2I and controls the frequency of an inverter 1B in such a manner that the power P2I of the inverter 1B can be arbitrarily output in response to a set value Pset through the phase shifter 10B and control circuit 11B. When interchanging the power from system A to system B, the set value Pset is so set that the power P2I flows from the inverter 1B to the system B. As a result, the inverter 1B is frequency-controlled and the power is released to the system B. Thus, voltage VDC drops and this is compensated by the inverter 1A in control and power is interchanged from the system A to system B.

Title: Servo track writing system
Inventor: YAMAZAKI ETSUROU
IPC: G11B23/30
Filed: 1983-03-17
Abstract: PURPOSE:To correct an error component synchronized with a rotation period to improve write precision by storing a position error component which is reproduced and detected from the position information of a determined track and correcting the position of a servo track in real time by the position error component when information is written on a servo track. CONSTITUTION:After servo data is written on a preliminarily determined number of tracks, the extracting processing of the position error component synchronized with the rotation period is started. A random component of a sampled position error signal is eliminated to extract the error component synchronized with the rotation period (T) to store in an RAM28. Obtained error component synchronized with the rotation period are read out from the RAM28 at the point of time corresponding to a sampling point, namely, in real time by the control of a processor 13 and is supplied to an adder/subtractor 20 through an input/ output port 17 and is added to a track position signal from a laser length measurer and is used for the driving of a linear reciprocation driver 6. Consequently, a head 2 writes information on the servo track without the error component synchronized with the rotation period.

Abstract: PROBLEM TO BE SOLVED: To reset peak hold voltage at high speed and reduce the fluctuation of an offset amount, by providing a discharge switch element or the like for controlling the discharge state of a voltage hold element (capacitor). SOLUTION: Discharge switch elements SW2, SW3 for controlling the discharge state of a capacitor C1 are provided, when a reset signal is inputted, a timing control circuit 2 controls the switch elements SW2, SW3 so that the capacitor C1 is in a non-charged state. In addition, a comparison circuit CMP1 compares the voltage and bias voltage of the capacitor C1, and in the case where the voltage of the capacitor C1 is high, the switch elements SW2, SW3 are controlled so that the capacitor C1 is in a discharged state. As a result, at the time of resetting, since the capacitor C is surely discharged up to the bias voltage through the switch elements SW2, SW3, discharge can be performed at high speed, and the high speed of resetting can be contrived.

Title: Concrete producing method and device therefor
Inventor: MERUBUIN ERU BURATSUKU
IPC: B28C9/00
Filed: 1980-04-04
Abstract: A slurry reclamation system for use with a concrete ready-mix plant which enables 100% reclamation of the constituents of concrete mix returned to the plant site by vehicles. Returned concrete mix is dumped into an inlet hopper having a screw classifier for removing aggregate and coarse sand, and a weired channel enabling gravity flow of the water, cement fines and sand fines constituents into a slurry vessel. The slurry in the vessel naturally separates into clarified water and concentrated slurry, and agitators are provided for periodically stirring up the slurry to maintain the cement fines active. The slurry vessel is sized in such a manner as to guarantee complete consumption of slurry returned during a day's production by the end of the following production day, the volumetric capacity of the vessel being related to the total average volume of water used to produce fresh concrete during a representative production day. An autochangeover unit automatically switches the water supply to truck washout stations and the screw classifier between normal plant supply water and the clarified water in the vessel, depending upon the level of the latter. The system enables substitution of slurry for cement fines alone, sand alone, water alone, or any combination of these concrete constituents in accordance with the percent activity of the cement fines in the slurry and production demand.
